To afl/ZZV whom it may concern:

`Be it'k'noW-n that I; JAMES W. WELDON, a'

citizen of the United States. Yand 'a resident of Toledo, in thecountyofLucas and State of 'Ohio, have invented certain new and usefulvImprovementsv inHeating-Stoves g and I do hereby declare the followingto be a full,

' clear, and exact description of the invention, .such as will enableothers sk'lled in the art to which it appertainsto make 'and use thesame, reference being had to the accompanying drawings, and to thefigures-of reference marked thereon', whichform a part of this'specification.

My invention relates `to heating-stoves of the class having abase-iiuesection through which'the highly-heated gaseous products of combustionmay be directed rior to being expelled from the stove throug theexit-flue.

The object. of the invention is the provision in a stove of this kind ofa series of air- I ues adapted to receive cold air and expel it yso tothe atmosphere ina 'highly-heated state, said iiues being so arrangedlrelative to the ash-pan section and the descending, base, and ascendingiues of the stove as to utilize the maximum heat-radiating surface ofsuch arts for the heating of cold air, whereby to increase theefficiency and commercial value of tne stove. f i

The operation, construction, and arrange# ment of the parts of theinvention are fully described in the following specification and Which-Figure 1 is a central vertical section of the stove embodying myinvention taken on the dotted line a: in Fig. 2. Fig. 2 is a rearelevation of the stove with a portion of the casing broken away. Fig. 3is yan irregular cross-section on the line w in Fig. 1, and

illustrated in the accompanying drawings, in

'F.ig. 4 is a partial vertical section on the lines y y in Figs. 2 and3.

Referring to the drawings, 1 designates the combustion-chamber', 2 theashfpan section,

and 3 the horizontal or prostrate base-flues of any ordinary type ofbase-burner. The base-lues 3 are separated by flue-strips 4 4 andcommunicate with the combustionchamber through the side descending iiues5 5 and with the exit through the central ascending flue 6 in theusual-manner. In the construction of stoves of this class it has beencustomary to locate the base-fines 3 immediately beneath the bottom ofthe -ash-pan section., so .that they are separated by a single par-'ation or ivan., while thiswau @partition becornes heated to a highstate, due 'to its proximity to the. conibustion-chaniber, it is notsuiiiciently heatedvto effect a further heating of the products ofcombustion descending tothe flues l3 from the coinbuStien-chamber, thusoccasioninga complete loss ofthe heatradiating efficiency of suchpartition'. In `order to utilize `this lost 4heat energy, I inteipose ahorizontal flue 7 between the bottom .of the ash-*pan section and thetop S of the flues 3,. as shown. The ilues 7 is substantially thewidthof the ash-pan section and hasits forward end provided 'with a broadmouth 9, opening to the atmosphere, whereby to receive c'old air, anditsreai' end coinmunicatingwith a narrowed vertical ilue 10,

which is disposed immediately in advance of 'the ascending exit-flue 6with its rear wall exposed to said iiue and its front wall'exposed tothe ash-panand combustion-chamber sections. The upper end of this iiueterminates adjacent the top of the stove and iso en, as

yart-11, to expel to the atmosphere t e air,

which becomes highly heated in yits passage therethrough. ,y

'It is apparent that the lower and rear walls' of the iiue 7 lOvare`heated to a high state by the passing of the highly-heated gases ofcombustion around the lease-'ihres 3 and upthe ascending flue 6 and.that'the top and front walls of'said iiue are highly heated from theash-pan and combustion-chamber sections, thus causing the air passingthrough said flue. to lbe acted on by the heat radiation from Yall ofsaid walls,l and consequently heated to avery high stateprior to itsexpulsion to the rooni. l y

In order to` further utilize the otherwise lost radiation surface ofthestove interior, I

make the flue-strips 4 4 hollow' to forni lues 12, 'with their bottomsopening below the stove for the admission of cold air thereto, as shownin F ig. 4. Therear end of each of these hollow flue-strips communicateswith a vertical liue 13, which is located between the contiguous sidedescending ilue 5 and ascendi1ig1lue 6 of the stove, and has its frontwall exposed to the ash-pan and combustionchamber sections, thus causingthe air which 'passes through the flue 12 13 to. be continuously actedon by the heat radiation from the gases of combustion from the time saidgases leave the combustion-chamber until they IOO have been expelled tothe exit-Hue from the the heat radiation' from the rear wall oftheashpan and combustion-chamber sections,

-The two vertical ilues 13 13 communicate products of combustion intosaid descending` flues.

The operation of the stove is as follows: The highly-heated products ofcombustion on leaving the eombustion-chamber` descend through the twoside iiues 5 5, pass ardhnd the hollow flue-strips 4 4, and ascendthrcufh the common iiue 6 to find an exit from tie stove, thus heatingthe lower and relai' wall of i l the air-flue 7 10 and bothl side wallsof' the air-flues 12 13. In addition to this the front walls of theilues -10 and 13 radiate heat to said ilues from the ash-pan andcombustioncliamber sections of the stove, and the upper wall or the topof the iiue. 7 radiates lieat'to said flue from the ash-pan section,thus utilizing all the available heat-radiating surface for the heatingof cold air taken in from the vroom and materially increasing theheating eiliciencly7 of the stove.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

-1. rIhe combination in a stove having communicating side descendingflues at its rear, horizontal base-fines, and an ascending flue disposedbetween the descending iiues, of vertical ilues separating each sidedescending flue from the ascending flue and open to the atmosphereadjacent their tops, and hollow flue-strips separatingthe base-fluesandv having their bottoms opening below `lthe stove and their rearendscommunicating with the contiguous vertical iiue, substan- @muy asdescribed. V

2. The combination in a stove having two communicating side descendingflues, horiv zontal base-flues, and an ascending flue tor the productsofcombustion, of a vertical airiiue dis vosed between each side descendingflue an thecontiguous side of'the ascending flue, the front walls ofsaid air-iiues forming a part of the rear wall ofthe ash-pan andconiustion chamber sections, and flue-strips separating the base-finesand having `their bottoms open to the atmosphereand their rear -eiidscommunicating with the vertical air-fines.

3. rl`he combination in a stove of horizontal base-flues, a centralascending and" two side .descending ilues communicating with thebase-fines and disposed at the rear of the stove, and a-verticalair-flue disposed between each side descending flue and the contiguousside of the ascending llue and having its side Walis forming thecontiguous side walls of the descending and ascending flues, saidair-flue having both ends open to the atmosphere.

4.- r l`he combination in a stove of horizontal base-ilues, a centralascending and two side descending fines communicating with thebase-fines and disposed at the rear side of the stove, a verticalair-flue between each side descending flue and the ascending lue andopen at its top to the atmosphere, said air-flues having their sidewalls forming the contiguous side walls of the ascending and descendinglflues 'andthcii' front walls e;\'- posed to the ash-pan andcombustion-chamber sections, and hollow flue-strips separatingthebase-fines and having their bottoms open to the atmosphere and theirrear ends communicating with the vertical air-fines, substantially asdescribed.

In testimony whereof I have hereunto signed my name to thisspecification in the presence of two subscribing witnesses.
